So here are my tips what i saw in iron games and i think were the biggest mistakes
1. Attacker side and not pushing/doing anything. So your entry fragger (the guy who tries to get first kill) fails or something happens i usually see 3-4 players just sit in one corner just not doing anything... then the time ends and nothing gets done or enemy just pushes and sprays all down. Now you have atleast two choices if you get stuck get pick by peaking or escape and try to push anothern site. But dont just stand hiding not doing anything
2. Not planting bomb or waiting 20secs when site is cleared and then die to rotation
3. Not speaking... if you have microphone... USE IT! give info and coordinate with team... "one heaven" thats it most simple info is good.
4. Crosshair placement.... always try to preaim for head
5. Learn your agent SOVA ARROWS etc.
6. Play as a team, if teammate doesnt want you to smoke mid or do something try something different
7. If your top fragger is on 1vs3 situation dont yell at hes ear "gogo plz go" or something....he is prolly better and knows what he is doing
8. Dont rush on defendet side everyround, play it defensively.... okay sometimes you can push but if you are iron you prolly wanna learn defence first.
9. Use your teammates abilities, tell cypher,brim to trap some spots that are difficult
10. Rotate fast, this game is really fast with rotations, be fast
11. USE SHIFT KEY if you arent in hurry, its so much easier to hear enemies and you cannot be heard. Oh the times i have wallbanged players who dont know this key
